Revolution is a film about changing the world. The true-life adventure of Rob Stewart, this follow-up to his acclaimed Sharkwater documentary continues his remarkable journey; one that will take him through 15 countries over four years, and where he’ll discover that it’s not only sharks that are in grave danger – it’s humanity itself. In an effort to uncover the truth and find the secret to saving the ecosystems we depend on for survival, Stewart embarks on a life-threatening adventure. From the coral reefs in Papua New Guinea and deforestation in Madagascar to the largest and most destructive environmental project in history in Alberta, Canada, he reveals that all of our actions are interconnected and that environmental degradation, species loss, ocean acidification, pollution and food/water scarcity are reducing the Earth’s ability to house humans. How did this happen, and what will it take to change the course that humanity has set itself on?
